Respuesta :
The probability of not drawing a pink bead is 1 - P(pink bead). This is 1 - 4/15 or 11/15. The probability is 11/15 = 0.733 = 73.33%.
Answer: The answer of this question is 11/15.
Probability
It is basically the likeliness of happening an event. The probability of happening an event is number of events/number of possible outcomes.
Calculation of probability:
In this question there are 7 purple beads, 4 blue beads and 4 pink beads and we have to find the probability of not drawing a pink bead. Probability of not drawing a pink bead is equal to the probability of drawing purple bead and probability of drawing pink bead.
So,
P(not drawing a pink bead)=P(drawing purple bead)+P(drawing pink bead)
=7/15+4/15
=(7+4)/15
= 11/15
Hence the probability that pink bead is not drawn is 11/15.
It concludes that lesser the number of events more the probability of not happening of those events.
